Pyramiden (meaning "the pyramid" in Swedish and other Scandinavian languages; called Пирамида, piramida, in Russian) is a Russian settlement and coal mining community on the archipelago of Svalbard, Norway. Founded by Sweden in 1910 and sold to the Soviet Union in 1927, Pyramiden was closed in 1998 and has since remained largely abandoned with most of its infrastructure and buildings still in place.

Set near the beautiful Wolgan Valley in New South Wales, Newnes is an abandoned oil shale mining settlement built by the Commonwealth Oil Corporation during the late nineteenth century. Two mines were established on north side of the Wolgan River. Workers even aimed to tunnel under a mountain to link up with other facilities in the Capertee Valley where conditions were better, but mining difficulties and low quality shale rendered the tunnel an elusive dream. 1906 saw the construction of retorts, distillation areas, oil storage tanks, workshops and a power station, the substantial remains of which still exist today.

Probably a stretch to call it a ghost town, but we have no tread for individual abandoned buildings (at least nothing which I could find with google) so I post it here anyway:

The abandoned Lyster sanatorium in Norway. It was built in 1902, 500m up in the mountain side and with a own private aerial tramway connecting it with the fjord. It have stood empty since 1991 and there are currently talks about demolishing it.
